gg- don't use BT Yahoo, but if Mr Senior goes with BT broadband he obviously could. Is is web access mail to which you refer? I don't want to complicate things too much and thought OE might be simpler.
Yes I use the web access mail from Yahoo, my home page is 'my Yahoo' home page which is set up with the functions in it I want and one of those functions is 'Yahoo mail preview' which automatically updates every time I go on line and shows what e-mails are in the inbox and to read them just click on them to open, you can set up folders to stash things into very easily.
